Referring first: to" the "embodiment oi rtherinvention shown RTE-iglilIBSil-tdfi inclusiveriit will be noted: that the reference numeral 1 5 'vdesigsu nates generally a needle carrying .case comprise ing'a body 16 andia 'captl'l.

The bores or-recesses '2 I 1 are open at the 7 top to. receive articles of magmnetic; material; such ior-examp1e,-:as,-pins,; needles or the like, andterminate short ofthebot tom of the body in the manner clearly shown in;

A permanent magnet in the form of a rod-523;

is secured in the bore 20 with. the-opposite ends flush with :the top a and bottom" surfaces of g the:

The; capiisof -"sufiicient length to: enable" needles of various lengths=to be igsupported in the ibody, 'and if desiredi'maybe formed; of a transparent material to display (the contents of the recesses? I The embodiment, of the: invention shown .3 i111;

Figures 4 'and*5 diifers fromtheconstructiompre viously described in that the7bore2fl and rodw23 are: omitted;- Also the body 16, iIlStBQtiGOfxhBY-II ing an enlargement I8 at the lower endy'istform'd larged= base I 8 providing anzannular shoulderi 9 drawing an article of magnetic-material the;

with a reduced portion 24 which intersects the lower ends of the recesses 2|. A permanent magnet in the form or a ring 25 is sleeved on the reduced portion 24 in a manner to close the lower ends of the recesses 2| and provide an annular shoulder 26 for engagement with the cap l'l. It follows from the above that the ring 25 forms parts of the side walls of the recesses 2|, and thereby functions to retain articles of magnetic material within the recesses 2 I.

Referring now to the embodiment of the invention shown in Figures 6 to 8 inclusive, it will be noted that the body 2'! is approximately double the length of the body portions l6 described above,

and the cap 28 is correspondingly greater in length. The body 21 is formed with aligned axially extending bores 29 closed at the adjacent ends by a web 30 and adapted to respectively receive permanent magnets in the form of rods 3| and 3| respectively. A plurality of recesses 32 are formed in the upper portion of the body in concentric relation to the magnet 3| and are open at the top of the body to enable articles of magnetic material to be inserted into the recesses 32.

As in the first-described form of the invention, the recesses 32 intersect the bore 29 throughout the lengths thereof to expose adjacent portions of the permanent magnet 3|. Thus the magnet 3| serves to retain the articles in position in the respective bores 32.

Additional recesses 33 are formed in the lower portion of the body 21 in substantial axial alignment with the recesses 32. The recesses 33 are open at the lower end of the body, and are adapted to receive spools of thread 34, and these spools are preferably formed of a suitable magnetic material. These recesses also intersect the adjacent bore 29 to expose portions of the permanent magnet 3| and permit the latter to contact the enlargements at the opposite ends of the spools 34 to retain the latter within the respective recesses 33.

The embodiment of the invention shown in Fi ures 9 and is similar to the first described form ofthe invention except that the center bore 29 and rod type permanent magnet 23 are omitted. As shown in Figure 9 the recesses 2| extend entirely through the body l6 and are closed at the lower ends by a plate 35. The plate 35 is in the form of a permanent magnet, and is secured in a recess 36 formed in the bottom wall of the body l6. 7

In each of the various embodiments of the invention it will be noted that portions of the permanent magnet form parts of the walls of the article receiving recesses, so that the articles of magnetic material inserted in the recesses are engaged by the permanent magnet and held in position. Also in each of the several embodiments, the permanent magnet or a portion of the latter is exposed at the outer side of the body to enable the use of the body in picking up articles of magnetic material.

What I claim as my invention is:
